This invention relates to printing chases. It is an object of the invention to provide a chase in which type may be inserted and held in position for printing in a great variety of ways, in order that the same chase may be used for difierent purposes and to satisfy different requirements, thus obviating the necessity of supplying a number of different chases for different purposes.

Other objects and advantages of the invention will appear hereinafter.

A preferred embodiment of the invention selected for purposes of illustration is shown in the accompanying drawings, in which,

Figure 1 is a top plan view of a chase.

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a side elevation.

Figure 4: is a section on the line 1- 1 of Figure 1, and

Figure 5 is a top plan view, similar to Figure 1, showing the chase arranged to receive and hold type in a different manner from that illustrated in Figure 1.

Referring to the drawings, the chase coinprises a rectangular frame 1, preferably of metal and having a handle 2 secured thereto by means of which the chase may be conveniently carried when inserting and removing it from a printing machine. The two opposite exterior side walls of the frame on either side of the handle may be provided with grooves 8 which are adapted to fit flanges or keys of: the machine in order that the chase may be held firmly in proper operative position.

Inasmuch as the position of the chase in the machine is fixed by the said grooves, it is desirable that the positioning of the type held by the chase should be very flexible in order that the printing may be of the desired size, in the desired location, and running in the desired direction. According to the present invention it is possible to satisfy each of these requirements in a single chase as will be explained hereinafter.

Preferably, the individual pieces of type are carried in type bars as explained hereinafter, and in order to hold the type bars, the interior walls of the frame 1 are each out 1927. Serial No. 207,051.

away to provide a ledge 4 which thus extends around the entire inner surface of the frame. Each of the inner walls of the frame is the samelength, so thatthe interior aperture is square and the type bars 5 are of a length to extend from one inner wall to the opposite inner wall, the outer end faces of the said bars being shaped to fit over the ledgest of the frame.

Each of the type bars is provided with a plurality of grooves 6 which form keyways to receive keys which are formed on the type in order that each individual piece of type may be held securely against lateral motion. The grooves 6 are preferably tapered at the bottom to cooperate with a similar tapered form in the type. The grooves 6 are spaced laterally at suitable distances depending upon the size of the bar so that when the type is inserted the individual pieces fit closely one against another; Furthermore, the type bars 5 are each provided with end flanges 7 which are of a length such that whenthe type is inserted with its key fitted in the keyway 6 the face opposite the key fits flush against the rear wall of the next type bar, or against the wall of the frame 1 so as to hold the type additionally against lateral movement.

' As will be observed in Figure 1, type bars of three different sizes are illustrated, the grooves 6 being spaced and the end-flanges 7 of each type bar being dimensioned to receive type of different sizes. As illustrated in Figure 1, two lines of relatively large size are provided, a third line of a somewhat smaller size is provided and a fourth line of still smaller size is provided, and thefiat follower spring 8 is provided to press the type bars againstone another and against the rear end wall of the chase. As illustrated in Figure 5, five lines of type of the smallest size illustrated in Figure 1 are provided, but as will be apparent, various combinations .of type bars of different sizes may be inserted and held in the frame by means of the follower spring 8, varying from a single line of very large type to five or even more lines of smaller type. Furthermore, it will be apparent that by properly spacing the type bars 5 a single line of any desired size of type may be used, and may be positioned within the chase wherever desired by filling in the remaining space with type bars of proper dimensions. Thus almost any desired combination of number of lines or size of type may be held in the chase by suitably positioning and spacing the type bars 5.

Furthermore'due to the fact that the interior of the frame 1 is square, the type bars 5 may extend. laterally acrosslthe frame 1 as illustrated in Figure 1 or may extend across the frame 1 in the opposite direction as illustrated in Figure 5. In this manner, by merely changing the direction of the type bars, the chase may be conditioned to print in either of two directions, and by merely reversing, the direction of the type bars, the type may be arranged to. print in two directions as arranged in Figure 1 or in two directions as arranged in Figure 5. Thus it will be apparent that if the user is supplied with a single chase and a plurality of type bars of various sizes and a supply oftype ofvarious sizes the chase may be conditioned to print with type of different sizes and in different locations, with-different numbers of lines and in different directions. 7

It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention: y

1. A printing chase comprising a rectangular frame having inner Walls of equal length, the exterior of said frame being provided with means to support the chase in a fixed position in a printing machine, and each of the inner walls of said frame being straight from end to end thereof, but shaped from top to bottom to receive and support type bars of a length to extend from one inner wall to the opposite inner wall whereby said type bars may extend across said chase and be supported thereon in any position in either of two directions.

2. A printing chasecomprising a rectangular frame having inner walls of equal length, the exterior of said frame being provided with means to support the chase in a fixed position in a printing, machine, and each of the inner walls of said frame being straight from end to end, but provided with a ledge adapted to receive and support type bars of a length to extend from one inner wall to the opposite inner wall whereby said type bars may extend across said chase and be supported thereon in any position in either of two directions.

3. A' printing chase comprising a rectangular frame having straight inner walls of equal length, type bars of a length to extend from any inner wall to any opposite inner wall, and means to support said type bars in any position along said walls in which they are inserted.

lar frame having inner walls of equal length,

type bars of a length to extend from any inner wall to any opposite inner wall, means to support said type bars in any position in which they are inserted, and means to press the said type bars one against another and against one wall of the chase to hold the said bars firmly in position.

5. A printing chase comprising a rectangular frame having inner walls of equal length, type bars of a length to extend from any inner wall toany opposite inner Wall, means to support said type bars in any position in which they are inserted, and a follower spring adapted to press the said type bars one against another and against one wall of the chase to hold the said bars firmly in position In testimony whereof, I have signed my name to this specification this sixteenth day of July, 1927.
